As part of the Smart Series, this model is tailored for remote accessibility and EasyAccess 2.0 allows you to instantly and securely communicate with the cMT-SVR from anywhere in the world. Monitor PLC operations, gather data, and remotely access your control system via the cMT Viewer App on your Apple/Android smart phone, one of our Smart displays, or your own tablet/laptop/PC.

The cMT Series supports connecting a barcode scanner to the HMI and displaying the scanned barcode data on the HMI screen. Read More >

The cMT Viewer application can also be run on any PC. This means that any computer on the network with a cMT device can easily view and control the system. A plant manager can connect to any cMT in their plant to get a real-time view of exactly what is occurring with that machine. Connection to the cMT is password protected so only authorized users can have access. Another cMT feature, Monitor Mode, allows plant managers to view live data from up to 50 connected cMT devices simultaneously.

An alarm condition from any device would immediately alert the operator, enabling quicker response rates and resolution to the issue. The cMT Viewer application can run on a traditional Windows® desktop or on panel PC to provide a supervisory control station with access to many subordinate machines. Explore cMT Viewer.

The cMT Viewer provides a way to monitor the cMT Series from a PC, Industrial Panel PC, iPad, and Android tablet or smartphone.

What is cMT Viewer?

cMT Viewer is a client application that enables users to view and control cMT devices and screens, quickly and easily. cMT Viewer runs the HMI project on the client device. Only application data is exchanged between the cMT hardware, acting as a server, and the client device. This client/server architecture offloads CPU intensive tasks such as rendering project graphics from the cMT hardware to whatever client platform is used to connect to it. The cMT hardware's CPU is freed up for tasks such as PLC communication. This enables multiple client devices to connect to a single cMT server with each client device providing an interactive and responsive user experience.

Print to a variety of printers using the CUPS (Common Unix Printing System)

EBPro uses CUPS (Common Unix Printing System) to print to a variety of printers using their PPD (Postscript Printer Description) files. Over 850 PPDs are provided for various HP printers. Additional printers can be added by placing their PPD file in the ppd folder under the EBPro directory.
The selected PPD file is downloaded to the cMT model along with the project file to allow the HMI to send print jobs to a printer connected over Ethernet or USB. Status registers can be assigned to display the printer status and error codes, and command registers can be configured to update the printer status, change the printer interface (USB or Ethernet), and change the IP address and port number.

The Media Player allows playback of media files on the HMI screen.

Media Player

The Media Player object available on select models allows playback of media files on the HMI screen. The media file is stored on a USB flash drive or SD card connected to the HMI. This is ideal for displaying maintenance instruction videos to operators. The media player supports the following formats: avi, flv, mov, mp3, mp4, mpg/mpeg, wav, wmv.

The cMT Series can connect to a MySQL database server on a PC. MySQL is a popular open source database that was originally developed by Oracle Corporation. It is used to add, access, and manage content in a relational database management system.

Select cMT models can be configured to send data log or event (alarm) information to a MySQL server. Synchronize sampled data to the remote PC using MySQL. With third-party software (such as Microsoft Office Excel or Indusoft Web Studio®) you can manage data received from the cMT and funnel it directly to your corporate office.
The Database Server object enables the HMI to connect to a MySQL database server on a PC. This allows the user to send data log or event log information to the MySQL database server.

OPC UA features cross-platform interoperability, unified access, standardized communication, and security. In this architecture, the cMT series HMI models with built-in OPC UA server play a key role as communication gateway and allow OPC UA clients to access HMI or PLC data by subscribing to tags to receive real-time updates.

cMT and OPC UA

Here is an example of OPC UA in action. In this configuration, a SCADA application can run on an Industrial Panel PC like the OMI6815A as an OPC UA client and use it to access data in the OPC UA server (implemented on cMT Series models), to receive data updates of the PLCs connected to the cMT HMI, regardless of which PLC brand is connected.

The cMT Server stores the recipes used by all on-site machines in a recipe database. When the user changes the data in the recipe database, the new recipe data will automatically be downloaded from the Server to the Clients. Similarly, when the user would like to change recipe on the Client HMI, the most recent data can be obtained from the Server.

Synchronize the HMI real-time clock with an NTP server or, when downloading to the HMI, with your PC's clock.

Time Synchronization with NTP Server

Enable time synchronization in the HMI via an NTP (Network Time Protocol) server so that the HMI real-time clock will periodically synchronize to the date and time on the NTP server. The HMI can also be configured to automatically adjust to daylight savings time.

The VNC Viewer object in our configuration software allows an HMI to monitor and control another HMI using VNC (Virtual Network Computing).
Example: An automotive manufacturer has several 4.3" HMIs at various points along an assembly line monitoring sub-assembly processes. A 12" HMI is at the end of the line and the customer wants to monitor the 4.3" HMIs with the 12" HMI.
The VNC Viewer allows the 12" HMI to view and control the 4.3" sub-assembly HMIs quickly and seamlessly without interrupting the function of the 12" HMI.

Video from a USB camera connected to the HMI can be streamed and viewed in a web browser on a PC or mobile device.

Web Streaming from a USB camera

Many HMI models support connecting a USB camera to the HMI and viewing the video on the HMI screen. This is useful for monitoring a process or area of the manufacturing floor that is difficult to see from the operator's position. Now you can log on to the HMI with a web browser via its IP address and stream the video from the USB camera to a PC or mobile device. Simply enable web streaming on the HMI and enter the HMI's IP address in your browser to view the video.
